INSTALLATION FOR PREPARING AMMONIUM SULPHATE SOLUTION THROUGH DIRECT MIXTURE OF SULPHURIC ACID AND AMMONIA Russian patent published in 2010 - IPC C01C1/242 

FIELD: chemistry.

SUBSTANCE: invention pertains to inorganic chemistry which relates to synthesis of mineral fertiliser and specifically to process installations for preparing ammonium sulphate by directly mixing sulphuric acid with ammonia gas. The installation for preparing an ammonium sulphate solution has supply pipes and inlet units for sulphuric acid and ammonia gas, a circulation pump and a collector-container on a suction drum and a heat exchanger. The units for inlet of sulphuric acid and ammonia gas are made in form of two tubular injector mixers inserted into the circulation pipe and connected to the input and output of the heat exchanger. The sulphuric acid and ammonia gas supply pipes are connected to socket pieces for inlet of streams of sulphuric acid and ammonia into the tubular injector mixers.

EFFECT: design of a closed non-waste installation, which prevents emission of the ammonia gas phase into the atmosphere; reduced loss of valuable material; lower capital expenses on construction.
